Les Rotations Et Les Quaternions

La construction du corps non commutatif H de quaternions est une variante plus compliquée de la construction du corps commutatif C de nombres complexes. Donc on commence en rappelant la construction de C à partir de R. Les nombres complexes s’écrivent a+ bi avec a, b ∈ R. Donc C est un espace vectoriel sur R de dimension 2 avec base {1, i}. La loi d’addition de C est celle que C possède en tant...

Maladie de Johne (Paratuberculose) chez les caprins et les ovins en Iran: L'aspect épizootologique, clinique, pathologique et diagnostic au laboratoire

Mehdi Tavassoli

54 patients with localized or primary malignant melanoma had circulating cytoplasmic antibody. A few patients formerly positive but who had converted to negative, and some who on clinical grounds had a primary lesion but who had negative tests for cytoplasmic antibody, were found to have developed metastatic lesions. It is postulated that the halo naevus represents a seldom seen interim stage n...

Mehdi & Boubaker_2012

In this paper, a novel robust tracking control law is proposed for constrained robots under unknown stiffness environment. The stability and the robustness of the controller are proved using a Lyapunov-based approach where the relationship between the error dynamics of the robotic system and its energy is investigated. Finally, a 3DOF constrained robotic arm is used to prove the stability, the ...
